-x=-3+y
Add y to both sides.
-x=y-3
The equation is in standard form.
\frac{-x}{-1}=\frac{y-3}{-1}
Divide both sides by -1.
x=\frac{y-3}{-1}
Dividing by -1 undoes the multiplication by -1.
x=3-y
Divide -3+y by -1.
-y=-3+x
Add x to both sides.
-y=x-3
The equation is in standard form.
\frac{-y}{-1}=\frac{x-3}{-1}
Divide both sides by -1.
y=\frac{x-3}{-1}
Dividing by -1 undoes the multiplication by -1.
y=3-x
Divide -3+x by -1.
